"Riding motorcycles isn't natural.
It's dangerous and abhorrent behavior.
Anyone who would willing endanger their lives just for 'fun' is sick in the head.
We should put it to a vote and have it outlawed."
Do you have any idea how easy it would be to get a motion to ban motorcycling, on the basis of it being dangerous? Or insert <bungee jumping/parachute jumping/rock climbing/motorsports>
There are an awful, awful lot of things that minorities do that the majority frowns upon.
The Constitution was created to protect the rights of individuals to partake in any risky, optional lifestyle they choose, as long as it does not harm anyone else. Even if such lifestyles are dangerous to themselves.
Let alone lifestyle decision over which they have no choice, that do not affect others directly.
Homosexuals being allowed to marry will not change my daily routine AT ALL. Nor does other people jumping out of planes/climbing rocks/going hunting etc. etc. affect me at all.
But Prop 8 is based upon 'I don't like what you're doing, so I'm going to make a law to stop you having the same rights as me', which is utterly, utterly against the founding principles of America.
The WHOLE POINT of America being founded in the first place, was freedom to express yourself as long as it does not harm anyone else.
Seriously, that's the Constitution in a nutshell.
If you think it's OK to put a ballot together restricting the rights of a minority of the population, then you also agree it's OK to put a ballot on the books to ban motorcycling/parachute jumping/playing cards on a Friday.
There's a huge difference between writing laws to protect you from danger from others' activities (e.g. having a human man-hunt) and laws to protect you from activities of others you simply don't like.
If we go down the road of putting things on the ballot we don't like, very quickly George Orwell's 1984 will seem like a bastion of freedom of expression in comparison.
If you want to start down the path to a homogenized society where only the social mores of the absolute majority are the rule, then go ahead. Sooner or later, the majority will start deciding stuff that you do, is unsafe/unsanitary/unwanted, and will vote to ban it.
Including religion.
